The third student retreat within the Helmholtz program "Matter and Technologies" is a meeting of PhD students to get to know each other and to exchange ideas and solutions. It will take place just before the third annual meeting of this Helmholtz program. We would like to start the day at 1 pm with scientific sessions dedicated to introductory or overview talks, where students may present their work to a “non-expert” audience. The goal is that the students get an impression which variety of fields of work constitutes the program “Matter and Technologies”. In the evening, we will organize a get-together. On the second day, we will have a discussion on issues which are important to PhD students in today’s perspective. Finally, we will get a GSI/FAIR tour.
